| Abstract: | Water inrush from the bottom coal layer in mining work faced now is rather serious in Northern China coalfield, which constraints seriously the normal economical benefits. Aiming at the characteristics of water inrush up to the mining working surface through coal bottom layer, the paper puts forward information method to solve water inrush problem and sets up information criterion. A lot of examples have been verified and satisfactory effect has been obtained. |
